<p>I do not see any reason why the added command could affect flashing or resetting the device, At worst it wouldn't change the base behavior. I do not have the hardware(<code>frdm-kw41z</code>, <code>frdm-k64f</code>) to test today but I will tomorrow, I will trust <a class="user-mention" data-hovercard-type="user" data-hovercard-url="/hovercards?user_id=241401" data-octo-click="hovercard-link-click" data-octo-dimensions="link_type:self" href="https://github.com/cladmi">@cladmi</a> restults with <code>frdm-k22f</code>.</p>
